Intersystem grounding clamp with serrated gripping surfaces and a plurality of grounding terminals
An intersystem grounding clamp including two clamp halves with flat mating surfaces at their ends and a recessed area at their centers. The recessed areas include teeth thereon to form opposing serrated gripping surfaces for securely gripping a water pipe or grounding rod. Through holes and clamping screws are provided through the clamp halves at the flat mating surfaces to connect the clamp halves in a clamping assembly and enable tightening of the grounding clamp to a pipe or rod. The clamp halves include a first clamp half and a second clamp half. The second clamp half includes a plurality of grounding terminals thereon for accepting grounding wires from equipment. The grounding terminals include open bores laterally through the second clamp half and threaded terminal screws screwed into the second clamp half and oriented to intersect the open bores.
1. A grounding clamp comprising:
two mating clamp halves including a first clamp half and a second clamp half, each of said clamp halves including a body having a facing side, a distal side, two lateral sides, and two ends;
said facing sides of said clamp halves including flat mating surfaces and a recessed area between said flat mating surfaces;
a serrated gripping surface on said facing side of each of said clamp halves;
clamping screws through said bodies of said clamp halves for holding said clamp halves together in an adjustable clamping assembly;
said distal side of said second clamp half including a plurality of grounding terminals for accepting secure attachment of grounding wires thereto;
said first clamp half includes an arm extending from said distal side of said clamp body;
an open bore extending laterally through said arm on said first clamp half;
a grounding terminal screw in said arm and oriented to intersect said open bore of said arm;
said grounding terminals of said second clamp half and said grounding terminal of said arm of said first clamp half oriented toward said facing sides of said clamp halves;
said clamping screws include heads;
said smooth bores of said second clamp half include a wide entry bore extending from said distal side of said second clamp half, said wide entry bore adapted to accommodate said heads of said clamping screws of said adjustable clamping assembly;
open bores extending laterally through said body of said second clamp half; and
bosses extending from said distal side of said second clamp half, said bosses aligned with said open bores extending laterally through said body.
2. The grounding clamp of claim 1 wherein
said second clamp half includes smooth bores extending through said body;
said first clamp half includes threaded bores extending through said body; and
said clamping screws are adapted to turn freely in said smooth bores of said second clamp half and engage said threaded bores in said first clamp half thereby enabling adjustment of said first clamp half with respect to said second clamp half.
3. The grounding clamp of claim 1 wherein said serrated gripping surfaces include two parallel ridges and a plurality of teeth on said ridges.
4. The grounding clamp of claim 3 wherein
each of said bodies of said clamp halves include a base; and
said parallel ridges extend from opposing sides of said base and are oriented longitudinally along said body.
5. The grounding clamp of claim 1 wherein said grounding terminals include threaded terminal screws screwed into said second clamp half and oriented to intersect said open bores.
6. The grounding clamp of claim 1 wherein said grounding clamp includes at least four of said grounding terminals.
7. The grounding clamp of claim 2 wherein
said first clamp half includes bosses extending from said distal sides of said body; and
said threaded bores of said first clamp half extend through said bosses.
8. The grounding clamp of claim 3 wherein said plurality of teeth on said ridges includes at least 10 teeth per inch of length of said ridges.
9. The grounding clamp of claim 1 wherein said clamp halves are constructed of metal.
10. The grounding clamp of claim 1 wherein the material of construction of said clamp halves are selected from the group including bronze and zinc alloy.
11. The grounding clamp of claim 1 wherein said serrated gripping surfaces of said 5 clamp halves will accommodate pipe diameters of trade size ½, ¾, and 1-inch.
12. The grounding clamp of claim 5 wherein said open bores of said grounding terminals are capable of accepting grounding wires of size 14 awg to 4 awg.
13. The grounding clamp of claim 1 including
a boss extending from said arm; and
said threaded terminal screw extends through said boss and said arm.
14. The grounding clamp of claim 5 wherein said
second clamp half includes a plurality of threaded bores in said distal side of said clamp body for accepting said threaded terminal screws; and
said threaded bores extend through said clamp body to said open bores.
15. The grounding clamp of claim 14 wherein each of said threaded bores is perpendicular to its corresponding open bore.
